The invention belongs to the technical field of vehicle parts, and discloses a control method of an air suspension system and the air suspension system.In the control method, when the difference value of the maximum value and the minimum value in height values detected by four height sensors is smaller than or equal to a first preset value, a vehicle is parked or runs on a stable road surface; at least one wheel of inflation or deflation is conducted on the four air bags, the height sensor can monitor the height of the frame before and after each wheel of inflation or deflation, and when the difference value of the maximum value and the minimum value in the four height values is larger than a first preset value, the vehicle runs on a bumpy road surface; the first pressure sensor is used for monitoring the pressure change of the air storage cylinder after one-time inflation or deflation so as to monitor the height change of the frame after one-time inflation or deflation. The requirement that a user can adjust the height of the vehicle frame when the vehicle is in any running working condition can be met. The air suspension system controlled by the control method of the air suspension system can adjust the height of the frame under any driving working condition.
本发明属于车辆零部件技术领域,公开了一种空气悬架系统的控制方法及空气悬架系统,本发明中,当四个高度传感器检测的高度值中的最大值和最小值的差值小于或等于第一预设值时,车辆停放或行驶在平稳的路面,对四个气囊进行至少一轮充气或放气,每轮充气或放气前后高度传感器均能够监测车架的高度,当四个高度值中的最大值和最小值的差值大于第一预设值时,车辆行驶于颠簸的路面,通过第一压力传感器监测一次充气或放气后的储气筒的压力变化来监测一轮充气或放气后的车架的高度变化。本发明能够满足当车辆处于任意行驶工况时用户均能够调整车架高度的需求。通过上述空气悬架系统的控制方法控制的空气悬架系统能够在任意行驶工况下调整车架高度。
